Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a cable conductor connection fitting. Background Technology

[0002] When conducting cable thermal cycling tests, it is necessary to connect the two cable conductors together for the test. Current technology commonly employs two methods to connect the cable conductors:

[0003] In the first method, the ends of the two opposing cable conductors are inserted into shackles, which are then used to tighten the conductors together, making installation quick and easy. However, due to the large gaps within the shackles, the cable conductor strands are prone to breakage, resulting in unstable connections, poor contact after long-term testing, increased heat generation, and ultimately, test failures.

[0004] In the second method, the ends of the two opposing cable conductors are inserted into the crimping tube from both ends to the appropriate positions, and then the crimping tube is tightened with crimping pliers. The connection is stable, and there is no issue of subsequent heat generation at the connection point. However, the two cable conductors need to be on the same axis, and the distance between the ends of the two cable conductors cannot be too large; the large crimping pliers used in the crimping process are heavy and difficult to move; and the crimping tube is a disposable item and cannot be reused, and the cost of the crimping tube is relatively high due to its pure copper material. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is to provide a cable conductor connection hardware that can achieve a stable connection of cable conductors and is reusable.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model provides a cable conductor connecting fitting for connecting cable conductors. It includes a connector and two clamping assemblies. The clamping assemblies are made of conductive material and include a first pressure plate, a second pressure plate, and a locking member. The first pressure plate and the second pressure plate are mated together to clamp the end of the cable conductor. The first pressure plate and the second pressure plate are detachably connected by the locking member. The two clamping assemblies are in contact with each other and are connected and fixed by the connector.

[0008] Preferably, the first pressure plate and the second pressure plate are joined together to form a clamping hole, and the clamping hole is open at at least one end. The end of the cable conductor is accommodated in the clamping hole and contacts the hole wall.

[0009] Preferably, both the first pressure plate and the second pressure plate are provided with locking holes, and the locking holes on the first pressure plate and the second pressure plate are detachably connected by locking components.

[0010] Preferably, the first pressure plate is provided with a connecting part, and the connecting parts of the two clamping components are in contact with each other and are connected and fixed by a connector.

[0011] Preferably, the connecting parts of the two clamping components are both flat and are in contact with each other in a stacked manner.

[0012] Preferably, the connecting portion of both clamping components is disc-shaped.

[0013] Preferably, the connecting part is provided with a connecting hole, and the connecting holes on the connecting parts of the two clamping components are connected and fixed together by a connector.

[0014] Preferably, the cross-sectional shape of the connecting hole is an arc shape.

[0015] Preferably, when the connecting parts of the two clamping components are in contact, the centers of the connecting holes on the two connecting parts are located on the same axis.

[0016] Compared with the prior art, this utility model has significant progress:

[0017] The cable conductor connecting fitting of this utility model has a clamping assembly made of conductive material. The clamping assembly clamps the ends of the cable conductors by means of a first pressure plate and a second pressure plate that are mated together. The clamping assembly is installed on the ends of the two cable conductors that need to be connected. The two clamping assemblies are in contact and connected and fixed by a connector, so that a stable and reliable conductive connection is formed between the two cable conductors. Since the first pressure plate and the second pressure plate are detachably connected by a locking member, the first pressure plate and the second pressure plate can be separated or locked by removing and installing the locking member, so that the clamping assembly can be loosened or clamped on the cable conductors, thereby realizing the reuse of the clamping assembly.

[0037] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.

[0038] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0041] like Figures 1 to 6 The image shows one embodiment of the cable conductor connecting fitting of this utility model. This embodiment of the cable conductor connecting fitting is used to connect cable conductors 01, so that two cable conductors 01 form a conductive connection.

[0042] See Figures 1 to 3 The cable conductor connecting fitting of this embodiment includes a connector 1 and two clamping assemblies 2. The two clamping assemblies 2 have the same structure and are used to clamp the ends of two cable conductors 01 respectively. The clamping assemblies 2 are made of conductive material and have good conductivity. When the clamping assemblies 2 clamp the ends of the cable conductors 01, the current transported by the cable conductors 01 can be conducted through the clamping assemblies 2 efficiently and with low resistance.

[0043] The clamping assembly 2 includes a first pressure plate 21, a second pressure plate 22, and a locking member 23. The first pressure plate 21 and the second pressure plate 22 are mated together to clamp the end of the cable conductor 01. The first pressure plate 21 and the second pressure plate 22 are detachably connected by the locking member 23. When the clamping assembly 2 is connected to the cable conductor 01, the end of the cable conductor 01 is accommodated between the first pressure plate 21 and the second pressure plate 22. The locking member 23 connects and fixes the first pressure plate 21 and the second pressure plate 22, and both the first pressure plate 21 and the second pressure plate 22 maintain pressure contact with the cable conductor 01, thereby applying a clamping force to the end of the cable conductor 01 and fixing the end of the cable conductor 01 between the first pressure plate 21 and the second pressure plate 22. The locking member 23 ensures the stability of the clamping assembly 2 and the cable conductor 01 in the connected state and prevents the connection from loosening due to vibration or external force. After removing the locking element 23, the clamping force between the first pressure plate 21 and the second pressure plate 22 disappears, allowing the first pressure plate 21 and the second pressure plate 22 to be easily separated. The entire clamping assembly 2 can then slide off or be removed from the cable conductor 01. The locking element 23 can be repeatedly disassembled and assembled onto the first pressure plate 21 and the second pressure plate 22, thus enabling repeated connection between the clamping assembly 2 and the cable conductor 01 without damaging the structure of the clamping assembly 2. Furthermore, the locking element 23 can be in the form of bolts, nuts, pins, or clamps.

[0044] A clamping assembly 2 is connected to each end of one of the two cable conductors 01. The two clamping assemblies 2 are then brought into contact and connected and fixed together by a connector 1. Thus, a conductive path is formed between the two cable conductors 01 through the contact of the clamping assemblies 2, which are made of conductive material, thereby enabling current transmission. Furthermore, the connection and fixation of the two clamping assemblies 2 by the connector 1 prevents separation or unstable contact due to vibration or external force, thus ensuring the continuity of the conductive connection between the two cable conductors 01. The connector 1 can be in the form of bolts, nuts, pins, or clamps.

[0045] Therefore, in this embodiment, the cable conductor connecting fitting has a clamping component 2 made of conductive material, which clamps the ends of the cable conductor 01 by the first pressure plate 21 and the second pressure plate 22 mating together. The clamping components 2 are installed on the ends of the two cable conductors 01 that need to be connected. The two clamping components 2 are in contact and connected and fixed by the connector 1, so that a stable and reliable conductive connection is formed between the two cable conductors 01. Since the first pressure plate 21 and the second pressure plate 22 are detachably connected by the locking member 23, the first pressure plate 21 and the second pressure plate 22 can be separated or locked by removing and installing the locking member 23, so that the clamping component 2 can be loosened or clamped on the cable conductor 01, thereby realizing the reuse of the clamping component 2.

[0046] See Figures 4 to 6Preferably, the first pressure plate 21 and the second pressure plate 22 are mated together to form a clamping hole 24. The clamping hole 24 is open at least one end. The end of the cable conductor 01 is accommodated in the clamping hole 24 and contacts the hole wall of the clamping hole 24. The first pressure plate 21 and the second pressure plate 22 each have mating surfaces that are mated together. The mating surface of the first pressure plate 21 is recessed inward to form a first cavity 210, and the mating surface of the second pressure plate 22 is recessed inward to form a second cavity 220. The first cavity (210) and the second cavity (220) each constitute a part of the clamping hole 24. When the first pressure plate 21 and the second pressure plate 22 are mated together, the first cavity 210 and the second cavity 220 are mated together to form a complete clamping hole 24. The clamping hole 24 is open at least one end, so that the end of the cable conductor 01 can be accommodated in the interior of the clamping hole 24 from the opening. In use, first fasten the end of the cable conductor 01 into the first cavity 210 or the second cavity 220, and then align and lock the first pressure plate 21 and the second pressure plate 22 together. Thus, the end of the cable conductor 01 is fixed in the clamping hole 24 formed by the alignment of the first pressure plate 21 and the second pressure plate 22 and maintains close contact with the wall of the clamping hole 24, achieving a stable connection between the clamping assembly 2 and the cable conductor 01.

[0047] Specifically, in this embodiment, the cross-section of the cable conductor 01 is circular, and correspondingly, the cross-section of the clamping hole 24 is also set to be circular to match the cable conductor 01, that is, the cavity shapes of the first cavity 210 and the second cavity 220 are both semi-cylindrical. When the first pressure plate 21 and the second pressure plate 22 clamp the end of the cable conductor 01, the outer peripheral surface of the end of the cable conductor 01 is tightly fitted with the hole wall of the clamping hole 24, thereby making the connection between the clamping assembly 2 and the cable conductor 01 more stable and the electrical conductivity better.

[0048] Furthermore, for cable conductors 01 with different outer diameters, if the outer diameter of the cable conductor 01 is smaller than the diameter of the clamping hole 24, copper foil can be wrapped around the end of the cable conductor 01 to increase the outer diameter, so that the outer diameter of the end of the cable conductor 01 is slightly larger than the diameter of the clamping hole 24. If the outer diameter of the cable conductor 01 is much larger than the diameter of the clamping hole 24, the monofilaments on the cable conductor 01 can be appropriately stripped to reduce the outer diameter of the end of the cable conductor 01 to be slightly larger than the diameter of the clamping hole 24.

[0049] See Figures 4 to 6Preferably, both the first pressure plate 21 and the second pressure plate 22 are provided with locking holes 25, and the locking holes 25 on the first pressure plate 21 and the second pressure plate 22 are detachably connected by a locking member 23. In use, the locking member 23 and the locking holes 25 cooperate to lock the first pressure plate 21 and the second pressure plate 22, so that the end of the cable conductor 01 is clamped and fixed between the first pressure plate 21 and the second pressure plate 22. This effectively prevents loosening of the connection due to vibration or external force, improves the mechanical stability of the connection between the cable conductor 01 and the clamping assembly 2, and the stable mechanical clamping helps maintain the continuity and reliability of current conduction, reducing the risk of poor contact. After use, simply remove the locking member 23 from the locking hole 25, separate the first pressure plate 21 and the second pressure plate 22, and the entire clamping assembly 2 can be slid off or removed from the cable conductor 01, thereby achieving convenient and quick disassembly between the clamping assembly 2 and the cable conductor 01.

[0050] Specifically, in this embodiment, multiple locking holes 25 are symmetrically provided on both sides of the clamping hole 24 along the axial direction of the first pressure plate 21 and the second pressure plate 22. The locking holes 25 are through holes that pass through the first pressure plate 21 and the second pressure plate 22 along the docking direction. The locking component 23 is a bolt and nut assembly. After the first pressure plate 21 and the second pressure plate 22 are docked, the bolts are inserted into the locking holes 25 and locked with nuts to fix the first pressure plate 21 and the second pressure plate 22. The multiple locking holes 25 are symmetrically and evenly distributed on the first pressure plate 21 and the second pressure plate 22, which helps to evenly distribute the locking force, so that the cable conductor 01 is clamped with balanced force. Locking with bolt and nut assembly is conducive to quick fixing or disassembly of the first pressure plate 21 and the second pressure plate 22, and facilitates the installation and disassembly of the clamping component 2.

[0051] See Figure 3 , Figure 4 Preferably, the first pressure plate 21 is provided with a connecting part 26, and the connecting parts 26 of the two clamping components 2 are in contact with each other and are connected and fixed together by the connector 1. In use, the two clamping components 2 are respectively connected to the ends of the two cable conductors 01, and the two clamping components 2 are in contact with each other through the connecting part 26. The current on the cable conductors 01 can be transmitted through the contacting clamping components 2, so that a conductive path is formed between the two cable conductors 01. Then, the connecting part 26 of the two clamping components 2 is locked and fixed by the connector 1, so that the two clamping components 2 will not be separated due to vibration or external force, so that the two cable conductors 01 are reliably conductively connected through the clamping components 2.

[0052] See Figure 3 , Figure 4Preferably, the connecting portions 26 of the two clamping components 2 are both flat and are in contact with each other in a stacked manner. By having the flat connecting portions 26 be in contact with each other in a stacked manner, the connection between the two clamping components 2 has a large contact area, which not only enhances the connection stability between the two clamping components 2, but also improves the electrical transmission efficiency between the cable conductors 01.

[0053] See Figures 1 to 4 Preferably, the connecting portions 26 of the two clamping components 2 are both disc-shaped. When the axes of the ends of the two cable conductors 01 intersect to form a certain angle, when the ends of the cable conductors 01 are connected by the clamping components 2, a certain angle is also formed between the two clamping components 2. Compared to the state where the two clamping components 2 are connected in parallel, the two clamping components 2 need to rotate the connecting portions 26 by a certain angle to achieve connection and engagement. In this embodiment, when the two clamping components 2 are connected, the two disc-shaped connecting portions 26 are stacked on top of each other and their axes coincide. When the two clamping components 2 rotate relative to each other, the edges of the two connecting portions 26 always remain in a state of overlap. Therefore, the edges of the connecting portions 26 will not interfere with the rotating clamping components 2, thereby enabling the two clamping components 2 to be connected at different angles to achieve an angled connection between the two cable conductors 01. For example, Figure 1 As shown, in one usage state, when the two cable conductors 01 are parallel to each other, the two clamping assemblies 2 are respectively connected to the ends of the two cable conductors 01 and are connected in parallel to each other through the connecting part 26; as Figure 3 As shown, in another usage state, when the two cable conductors 01 cross vertically, the two clamping components 2 are respectively connected to the ends of the two cable conductors 01 and are vertically cross-connected through the connecting part 26.

[0054] See Figures 1 to 4 Preferably, the connecting portion 26 is provided with a connecting hole 26a. The connecting holes 26a on the connecting portions 26 of the two clamping assemblies 2 are connected and fixed together by the connector 1. The cross-sectional shape of the connecting hole 26a is preferably arc-shaped. When the connecting portions 26 of the two clamping assemblies 2 are in contact, the centers of the connecting holes 26a on the two connecting portions 26 are preferably located on the same axis. In this embodiment, the connector 1 is a bolt and nut assembly. The connecting hole 26a is set to an arc shape. When the two connecting portions 26 are stacked and mated together, the centers of the two connecting holes 26a are located on the same axis. Therefore, when the two clamping assemblies 2 are connected in parallel or at any angle, the two connecting holes 26a always have overlapping parts in the axial direction of the connecting portion 26. Thus, the connector 1 can be inserted into the overlapping parts of the two connecting holes 26a and lock the two connecting portions 26 in place.

[0055] The usage process of the cable conductor connection hardware in this embodiment is as follows:

[0056] Preparation: Confirm whether the outer diameter of the cable conductor 01 matches the diameter of the clamping hole 24. If they do not match, wrap copper foil around the end of the cable conductor 01 or remove the monofilaments on the cable conductor 01 so that the outer diameter of the end of the cable conductor 01 is slightly larger than the diameter of the clamping hole 24.

[0057] Assemble clamping assembly 2: Fasten the end of cable conductor 01 into the cavity of the first pressure plate 21 and the second pressure plate 22, then align the first pressure plate 21 and the second pressure plate 22 together, and finally use locking member 23 to connect locking hole 25 to fix the first pressure plate 21 and the second pressure plate 22, and connect the ends of the two cable conductors 01 to clamping assembly 2.

[0058] Connecting clamping components 2: Place two clamping components 2 parallel to each other or at an angle, then stack the connecting parts 26 of the two clamping components 2 so that the center of the connecting hole 26a is on the same axis. Connect and fix the connecting holes 26a of the two clamping components 2 together through the connector 1 so that the connecting parts 26 of the two clamping components 2 fit together and lock and fix.

[0059] Check the connection: Check whether the two clamping components 2 are firmly fixed together and whether the cable conductor 01 is clamped evenly and stably.

[0060] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
